President Barack Obama's decision to authorize aerial surveillance of Islamic State in Iraq and Syria (ISIS) positions in Syria suggests that airstrikes employing manned and unmanned aircraft may not be far behind. All of this is right and proper. Yet danger lurks. The head of Syria's preeminent crime family—President Bashar Al Assad—waits, crocodile-like, for the American angler to tumble out of the boat. For Assad, opportunity knocks. If he handles matters correctly he can, with an assist from American inaction, return to polite society while others do the anti-ISIS heavy lifting for him.
